MILK-BOTTLE-LOCKING DEVICE.

Specification of Letters Patent.

Patented Sept. s, 1908.

door to which it is delivered to prevent the same from being taken byothers than those to whom it belongs. i The object of my inventionis toprovide a device for securing a milk bottle at the door to which itisdelivered and so constructed and arranged that no one except those havmgthe key of the device can remove the bottle therefrom.

A further object of my invention is to provide a device as mentionedWhicltmay be readily and quickly operated by the milkman in order tooccasion him no delay in his route.

A further object of my invention is to provide a device of the charactermentioned which shall be of simple construction, of low cost tomanufacture and one which shall not readily get out of order. A furtherobject of my invention is to provide a device of the character underconsider,

ation which shall accommodate bottles of d1? ferent heights.

lther objects will appear hereinafter. 4

With these objects in view my invention consists generally in a bracketto be secured to a door frame or other suitable place and adapted toreceive a bottle of milk, in combination with a ca adapted to slip downover the upper end and means for locking said can torevent removal ofthe bottle. i, My invention further consists in a bracket adapted to besecured to a doorframe or other suitable supp ortand havinga socket toreceive the bottom of a milk bottle in combination with a cap verticallyslidable on said bracket and adaptedto be pressed down over the upperend of the bottle and a lock for securing said cap in looking position.

,* *"My invention further consists 'inivjarious details of'ccnstructionand arrangements of parts all as will be hereinafter fully described and{particularly pointed out in the claims. Q'My invention will be morereadilyiunderstood 'j'by ijreference flto" thei accompanying and inwhich,

drawings forming a partof this specification Figure 1 is a sideelevation of a bottle locking device embodying my inventionin itspreferred form, portions of the device being shown in the section, Fig.2 is a vertical section on the line 2c-ar of Fig. 1', Figs. 3 and 4 aredetails of the locking device.

Referring to the drawings 1 indicates a bracket adapted to be secured toa door frame or other convenient place as by the screws 2. The bracket 1preferably comprises a vertical disposed plate extending horizontallyfrom the bottom of which is an arm 3 terminating in. the socket member 4in which the bottle is adapted to rest. The socket member 4 comprises abottle support ing portion 5 havin an upwardly extending annular flange6. fprefer that the socket be open at the bottom as at 7 to prevent theaccumulation of dirt therein, in which case the bottle supporting membercomprisesen annular inwardly extending flange.

8 indicates a bell shaped cap ada ted to.

slip down over the upper end or mout of the bottle. Fixed to the cap 8is a rod 9 terminoting in the vertical ortion 10. The portion 10 extendsthrough a box or lockpase 11 formed upon or secured to the bracket 1.

"The portion 10 is preferably squared as shown or otherwise. arranged toprevent turning or twisting in the lock case. Upon the lower end of therod or stem 10 is a sto 12 to revent the ca from being detache from t.'e bracket. The cap normally stands in the position shown in F1 1 butafter the milk bottle is inserted in die socket 4 it is in dotted linesinthe same figure. It is obvious that if the cap is locked in the latterosition it will be impossible to remove the bottle. Any suitable springlock may be.

used for this purpose, and in the drawings I pressed downwardly intotheposition shown have illustrated conventionally an ordinarycylinderlock havin the divided locking pins or tumblers. f As siowntherein the cylindrical plug 13 is which is noi'rna with the stem 10 bya spring 15 one end of provided with an ear orlug 14 y pressed intoengagement nng being secured or fixed to the plug thee and other end tothe casing. The stem .10 is provided with a into onefof which the ug 14is pressed when the cap 8 is moved' intoiloclring position.

air of notches 16, 15".

Milk bottles usually vary somewhat in height and, it is for this reasonthat I provide the two notches in the stem 10, the notch 16 bein engagedby the in 14 when a tall bott e is placed in the device, and the notch16 when a'shorter one is placed therein. It is obvious that any numberof notches may be employed in orderto accommodate bottles of variousheights. The upper faces oi the not ches are beveled or inclined asindicated at 17 to permit the stem and'the ca to move freely downward,but after having een once ressed down, they cannot be raised to re easethe bottle until the plug 13 is rotated with the proper key to withdrawthe lug 14 from the notch.

Having described my invention whet claim as .new and desire to secure byLetters Patent is:

1. In a device of the class described, a bracket adapted to be securedto a suitable support and havin a socket to receive the bottom of thebott e, a lockcase formed on said bracket, arod slidebly mounted in saidcase and having a curved upper end, a bell scenes she ed cap fixed tosaid curved upper end end adapted to be depressed over the mouth of thebottle, and means in said case for lock ing said rod, substantially asdescribed.

2. In a device of the class described, a bracket adapted to be securedtoe suitable support and havin a socket to receive the bottom of thebottle, a lock case formed on said bracket, a rod slidably mounted insaid case and having a curved upper end, a bell shaped cap fixed to saidcurved upper end and adapted to be depressed over the mouth of thebottle, e spring said case for locking sei rod and said cap in depressedposition, said rod being provided with a plurality of notches to receivethe same, substantially as described.
